Mello-Roos 101
Mello_Roos is actually slang for Community Facilities Districts. It comes from the names of the 2 legislators who introduced a bill in the state senate in the mid 1980's to allow a single land owner (master developer) to encumber the property with a bond issue for infrastructure improvements and then pass the debt on to the homeowner.
It allowed master deveoplers to put in infrastructure such as streets, storm drains, parks, schools,slopes, and other up front improvements with other peoples money.
Each CFD is different and there is a state mandated disclosure which sets forth the amount, length, and the annual increase that is allowed by the bond. It also includes the phone number of the issuing agency for a buyer to contact for information. Most CFDs are between 30 and 40 years in length so the first CFD's placed on planned developments in the late 80's are near the end of their life. Some can be payed off up front at a savings while others have to run the full period for to insure return for the investors.
CFD's are billed along with your tax bill but are not taxes since they have a beggining and an end. Perhaps "awgee" can comment on the deductibility or not.
Most planned communities mapped since the late 1980's will have one or more CFD's. The majority of real sale agents do not fully understand CFDs
